Outcomes of Coronectomy of Mandibular Third Molar: A Systematic Review
Keywords:
Third molar, Coronectomy, Inferior alveolar nerve injuryAbstract
Coronectomy is an alternative to complete removal of an impacted mandibular third molar. The technique removes only the crown, leaving the root in the socket, and preventing direct or indirect damage to the inferior alveolar nerve. Rationale of the study- Impacted mandibular third molar may be in close proximity to inferior alveolar nerve bundle, and extraction of the tooth may result in long-term or persistent paresthesia if the nerve bundle is injured. Alternatively, clinicians have attempted coronectomy of the third molars with variable success. The feasibility of executing a coronectomy procedure could be determined by weighing the pros and cons of randomized trials on the procedure. The study aims to weigh risk benefit ratio of considereing coronectomy over complete removal of third molar tooth. Systematic review was conducted including 15 relevant articles. The available evidence suggests that coronectomy is a technique that demonstrates a satisfactory level of safety, particularly within the immediate postoperative period. Further investigation is necessary to ascertain the long-term prognosis of the root.
